1.54.1. RHEA-2011:0086: enhancement update
* UDP packets were treated as if being connected: if multiple UDP packets reached the load balancer within a short period of time, all packets were sent to the same real server. This update adds One-Packet Scheduler, which load-balances the UDP packets. One-Packet Scheduler treats every UDP packet as a new connection, and picks a server based on the scheduling algorithm.

Users of ipvsadm are advised to upgrade to this updated package, which adds this enhancement.
